How to buy HD internet TV set-top box? Detailed assessment tells you how to choose

Today, high-definition Internet TV set-top boxes have entered millions of households, a scene of contending prosperity. In addition to well-known Xiaomi box, Haimeidi box, Kaibull box, Tianmin box and so on, in the face of a dazzling array of brands, models, chip solutions, hardware configuration, so that consumers take the trouble, so how to choose high-definition Internet TV box?

1, the network environment is decided

The network set-top box transmits signals through the network. Therefore, a reliable and stable network speed is a prerequisite. Current network set-top boxes require at least a total of 2-4 megabits of stable Internet speed to be used smoothly. If they are less than 2 megabytes, it is difficult to obtain a smooth viewing experience.

In China, the stability of the network provided by different network service providers is also different. Among them, the stability of the telecommunication network is the best, followed by Unicom, Railcom, and Mobile, followed by Great Wall Broadband. If the family has only 2 megabits of network speed, you can choose to use the Action Plan set-top box; if you have more than 4 megabytes of bandwidth (non-Great Wall,) you can choose the Android system products, such a box is too much, no longer say.

2, functional requirements

If you only watch TV live broadcasts and video on demand functions, you may choose to use Dyomaete, Yidian, or Yigerui to meet the demand and have a cheap price. If you also want to experience a large game, high-definition local playback, etc., 300-400 yuan box is enough.

3, chip solution

Currently on the market mainstream Android chips for Quan Zhi, Hass, Rockchip, Crystal morning four. The chip plan includes the A31, A31S of the whole ambition; RK3166, RK3188 and RK3288 that will come to the forefront of Ruixin Micro; K3V2 of Hass; S805 of Jing Chen. Among them, QuanZhi's chips are known for their GPU capabilities and low cost. Rockchip's microchips are respected for their powerful CPU performance and relatively low cost. Hass chips have excellent decoding capabilities, but their cost is high. The chip Chen's comprehensive quality is high. There is no weakness, so the cost is the highest.

4, CPU

Like a computer, the CPU is an important standard for checking the performance of a box. System response speed, video decoding speed, program running speed, and other basic functions are all linked with CPU performance. Most of the boxes on the market today are equipped with quad-core chips.

5, wireless receiving capacity

It is common for several mobile phones and several computers to have wireless signals in the home. It is easy for so many signals to interfere with each other. Not only does the box run unstable, but it also delays the speed of the box. Therefore, many families only need to retreat to the box to access the Internet to ensure signal stability. Is there any way to stabilize the signal without the use of network cables? The answer is yes, as long as the box itself has good shielding performance and the Wi-Fi antenna signal is strong. There will be no problem.

6, video support

After the agreement is supported, the next step is to talk about format support. After all, anyone who does not want to work hard will not be able to put it out. In addition to the more common MP4, WMA, and AVI formats, FLV, RM, VOB, 3GP, RMVB, etc., are also the best ones to support. Everyone can see the video formats it supports on the box's packaging, and compare whoever supports it.

7, heat dissipation

The box as a household product is an important piece of electrical equipment. The opening may be a day without moving the nest, and the battery life is particularly important. When you select the machine, it has a lot of cooling holes. When the body is operating for a long time, it won't burn hot. The body is metal and not very hot. It's a very good design. Most of the current box product casings are plastic, PC materials, and some are pure aluminum metal, superior heat dissipation. Finally, look at the power. The higher the power, the more power it consumes and the easier it is to generate heat.

Door Lock Motor

Door Lock Motor Characteristics 1. No direction: don't need to distinguish the door direction, left and right sides, both inside and outside the door, can be universal. (convenient purchase locks and reduce inventory).

2. Power: the power consumption is only equivalent to one 5 of the electric control lock, electric lock, 3 A magnetic lock power to open the door, often consumes 0.27 A. And spiritual lock unlock instantaneous current is less than 0.5 A, reduced the entrance guard, talkback host power consumption.

3. No collision: close the door without collision, reduces the choice of door closers requirements (not necessarily with 65 kg of door closers, door closers are free to choose to suit the door), to solve the building door because the door closers clash of the hydrodynamic force is too high, it is not easy to make the door more deformation, prolong the service life of the body.

4. The voice is light: close the door automatically locked, no noise, solves the noise due to electric control lock itself.

5. Life is long, life is up to 350000 times
